DocuSign Envelope ID: E380154C-A526-42C6-9A09-974E2B481BE1 City of Renton Department of Community & Economic Development Camellia Court Apartments Staff Report to the Environmental Review Committee LUA23-000361, ECF, CUP-H, SA-H, MOD Report of December 18, 2023 Page 2 of 8 ERC_CamelliaCourt_Final PART ONE: PROJECT DESCRIPTION / BACKGROUND The applicant proposes to construct a multi-family residential building located at 99, 101 and 107 Williams Ave S. The building and main entrance front onto Williams Ave S (Exhibit 2). Vehicle access to the on-site structure parking is proposed to be provided at the rear of the building (western façade) via a mid-block alley between Burnett Ave S and Williams Ave S and accessed from either Williams Ave S or S Tobin St. Alley access from Williams Ave S would be accomplished via an approximately a 180-foot (180’) long travel way or from S Tobin St via an approximately 390-foot (390’) long trave way. The project properties contain two (2) detached dwellings and one (1) single story commercial building. All will be removed for the project. The applicant is requesting a Hearing Examiner Conditional Use Permit, a Hearing Examiner Site Plan Review, Environmental Threshold Determination (SEPA), a modification to roadway standards and a modification to the attached dwelling unit minimum standards to construct a six (6) story 78,663 square foot multi-family apartment building. The project would provide 72 dwelling units with 72 on-site parking stalls (Exhibit 3). Fifty-six studio units, 14 two (2)-bedroom units and two (2) three (3)-bedroom units are proposed. The structured parking constitutes two (2) levels: one (1) basement level and one (1) ground floor level. The basement level would also include resident storage areas. The ground floor level would also include a hospitality center, lobby, tenant library/internet lounge, rental and manager’s office, fitness center and mail/package facilities. Exterior tenant amenity space would be provided on the second floor with a terrace; the terrace includes seating, plantings, televisions, gas barbeque facilities and a gas firepit. The building would have a frontage along Williams Ave S of 149 feet six inches (149’6”). The building’s depth would be 109 feet six inches (109’6”). The building’s highest point, which would be to the top of the elevator shaft, is 71 feet (71’) above grade (Exhibit 4). Exterior cladding materials include a ground floor CMU veneer with glazing along Williams Ave S; the veneer wraps around to the north and south facades. An exterior concrete wall is proposed along the remainder of the ground floor facades. Exterior cladding on the upper floors include fiber cement lap and panel siding, window trim, vinyl windows with trim, aluminum panels and asphalt shingles on the roof. The applicant proposes to accommodate vehicle parking within on-site structured parking. The structured parking constitutes two (2) levels: one (1) basement level and one (1) ground floor level. A modification was requested for required street improvements that would allow the curb line to remain in its current location along Williams Ave S. The applicant would then dedicate approximately two and a half feet (2.5’) along the frontage to provide the required 12-foot (12’) wide sidewalk and street trees in grates. The project’s density is at 185.7239 dwelling units per acre (Exhibit 5). Within the CD zone the maximum density is 150 dwelling units per acre but can be increased to 200 dwelling units per acre subject to conditional use permit approval. Application for a conditional use permit to increase the density was submitted with the application materials. The applicant has also requested a modification to the applicable code within RMC 4-4-155, Attached Dwelling Units – Minimum Standards to allow for the calculation of habitable area to include the entirety of a unit rather than only the living, sleeping, eating or cooking areas as required through RMC 4-4-155C, Habitable Space. PART TWO: ENVIRONMENTAL REVIEW In compliance with RCW 43.21C.240, the following environmental (SEPA) review addresses only those project impacts that are not adequately addressed under existing development standards and environmental regulations. A. Environmental Threshold Recommendation Based on analysis of probable impacts from the proposal, staff recommends that the Responsible Officials: Issue a DNS-M with a 14-day appeal period DocuSign Envelope ID: E380154C-A526-42C6-9A09-974E2B481BE1 City of Renton Department of Community & Economic Development Camellia Court Apartments Staff Report to the Environmental Review Committee LUA23-000361, ECF, CUP-H, SA-H, MOD Report of December 18, 2023 Page 3 of 8 ERC_CamelliaCourt_Final B.

Environmental Impacts The Proposal was circulated and reviewed by various City Departments and Divisions to determine whether the applicant has adequately identified and addressed environmental impacts anticipated to occur in conjunction with the proposed development. Staff reviewers have identified that the proposal is likely to have the following probable impacts: DocuSign Envelope ID: E380154C-A526-42C6-9A09-974E2B481BE1 City of Renton Department of Community & Economic Development Camellia Court Apartments Staff Report to the Environmental Review Committee LUA23-000361, ECF, CUP-H, SA-H, MOD Report of December 18, 2023 Page 4 of 8 ERC_CamelliaCourt_Final 1. Earth Impacts: The proposed improvements include the construction of a six (6) story multi-family apartment building to include two (2) levels of structured parking (1 below grade and 1 at grade) and five (5) stories of residential dwelling units. The building will be 78,663 gross square feet with a 11,213-square foot building footprint. The project site is currently improved with two (2) single-family residences and a commercial office building (Exhibit 6). Per the Environmental Checklist (Exhibit 7) the entire property would be disturbed during construction and would result in approximately 7,375 cubic yards of cut. The subject property is located in a Geologically Hazardous Area, specifically a High Seismic Hazard Area. A geotechnical report (Exhibit 8) authored by Geotech Consultants, Inc, dated May 24, 2022, was provided with the land use application. Geotech Consultants, Inc completed subsurface reconnaissance of the site on May 9, 2022, in three (3) locations on the site. The results indicate that beneath the ground surface, loose alluvial silt and sand, containing scattered organic layers were encountered to a depth of 10 to 16 feet (10’ – 16’) where medium-dense sand and gravel were revealed. The sand and gravel layer was observed to be highly variable in density, exhibiting a medium-dense and denser consistency in the northwest and southwest portions of the project site. In the center of the project site medium-dense soils were not revealed until a depth of 16 feet (16’). The medium dense and denser sand and gravel continued to depths of 25 to 36 feet (25’ – 36’). Groundwater seepage was encountered at approximately 16 feet (16’) during subsurface exploration. Based on previous work done by Geotech Consultants, Inc in the vicinity, it is estimated that the expected seasonal high groundwater level is at approximately 15 to 16 feet (15’ – 16’) below the ground surface. The submitted geotechnical report states that liquefaction during a Maximum Considered Earthquake (MCE) would result in a total calculated ground settlement in the order of up to four to six inches (4” – 6”). A recommendation to use mat foundations could reduce the settlement to two to four inches (2” – 4”) of settlement. Additional recommendations include using augercast concrete piles because of potential caving conditions and/or significant groundwater, retaining walls backfilled on only one side be designed to resist lateral earth pressures and soldier pile walls to reduce potential for excessive caving and adverse impacts to adjacent streets, utilities and structures. Due to the report’s confirmation of the liquefaction potential for the site and recommendations for mitigating its effects during an earthquake, Staff recommends, as a mitigation measure, the applicant comply with the recommendations of the geotechnical report, prepared by Geotech Consultants, dated May 24, 2022, and any future addenda. Staff recommends the applicant’s geotechnical engineer review the project’s construction and building permit plans to verify compliance with the geotechnical report. The geotechnical engineer shall submit a sealed letter stating they have reviewed the construction and building permit plans and in their opinion the plans and specifications meet the intent of the report(s). Mitigation Measures: a. The project shall comply with the recommendations of the geotechnical report, prepared by Geotech Consultants, dated May 24, 2022, and any updated report(s) associated with the building and construction permits to ensure compliance with the intent of the initial reports. b. The applicant’s geotechnical engineer shall review the project’s construction and building permit plans to verify compliance with the geotechnical reports. The geotechnical engineer shall submit a sealed latter stating that they reviewed the construction and building permits and in their opinion the plans and specifications meet the intent of the reports.

Air Impacts: Temporary impacts to the air from typical earthwork construction equipment and vehicle s such as dust and exhaust is expected during construction. Temporary construction odors during finishing work, such as drywall and painting is also expected. Once construction is completed there will be emissions from tenants’ vehicles. The construction impacts are not anticipated to be significant. Dust control can be mitigated using temporary erosion control measures, watering or other measures to remediate impacts as needed. Proposed measures from the Environmental Checklist include sweeping and spraying the street with water as necessary during construction to reduce dust impacts, requests to not idle vehicle motors during deliveries and requesting framing crews to use electric instead of gas air compressors. Additional temporary emissions control can be conditioned through the civil construction permit. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 3. Water a. Ground Water Impacts: COR Maps identifies the project area as being with the Zone 1 Downtown Wellhead Protection Area. Per the Environmental Checklist no groundwater will be withdrawn and no waste material will be discharged into the ground. The project does not include a prohibited facility as outlined in RMC 4-3-050, Critical Area Regulations. If more than 100 cubic yards of fill are imported, a fill material source statement is required that is certified by a professional engineer or geolog ist licensed by the State of Washington identifying each source location of the fill. Erosion control measures are proposed following standard BMPs. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. b. Storm Water Impacts: A preliminary Drainage Plan (Exhibit 9) and Technical Information Report (TIR) (Exhibit 10), dated August 2, 2023, was submitted with the Land Use Application. Based on the City of Renton’s flow control map, the site is within the Peak Rate Flow Control Standard area (matching existing site conditions) and falls within the Lower Cedar River drainage basin. The development is subject to Full Drainage Review in accordance with the 2022 Renton Surface Water Design Manual (RSWDM). The applicant has proposed to connect to the City of Renton’s storm drainage system within the abutting public alley right-of-way to the south. A Level 1 downstream analysis was performed as part of the TIR. The downstream drainage paths were field inspected on January 1, 2023, for existing drainage problems; the drainage area was evaluated by reviewing the Documented Drainage Complaints withing one (1) mile of the downstream flow paths which has not shown any complaints within the last 10 years. The project will result in a 0.125 cubic feet per second (cfs) increase in the 100-year peak flow. As the peak flow is less than a 0.15 cfs increase, no flow control facilities are required for the project. Additionally, the project is exempt from providing water quality treatment since less than 5,000 SF of new plus replaced pollution generating impervious surface is created. Erosion control measures are proposed per the temporary erosion and sediment control (TESC) plan and Best Management Practices (BMPs). The stormwater system shall be designed in accordance with the RSWDM that is current at the time of the civil construction permit application. The City’s adopted 2022 RSWDM is anticipated to mitigate stormwater impacts associated with the development.

Nexus: Not applicable. 4. Vegetation Impacts: The project site is encumbered with two (2) detached dwellings and one (1) commercial office building. The applicant provided an arborist report (Exhibit 11) from Advanced Arboricultural Assessment, dated March 13, 2022. It identifies a Mountain Ash and an English Holly on-site; two (2) existing street trees are located within the adjacent Williams Ave S right-of-way. The remainder of the on-site vegetation is lawn. All existing on-site vegetation is proposed for removal. The City also received public comment (Exhibit 12) from the Duwamish Tribe, dated November 10, 2023, strongly recommending that only native vegetation be used. Per the conceptual landscape plan (Exhibit 13) 14 Oil-Seed Camellia trees are proposed in common areas and balconies on the second floor. Additionally, bushes (Cherry Laurel, Japanese Camellia, Creeping Rosemary) and ornamental grasses (Black Mondo Grass, Horsetail Reed) are proposed as supplementary plantings on the second level and at the front entrance on the ground floor. Native vegetation can be required to be installed where appropriate through the Site Plan Review application. The applicant would be required to meet Tree Retention and replacement standards which include but are not limited to 30 percent retention (or replacement if approved) and minimum 30 tree credit per acre. Code required tree retention/credit and landscaping standards are anticipated to mitigate tree canopy and landscaping impacts. Mitigation Measures: No further mitigation is recommended. Nexus: Not applicable. 5. Aesthetics Impacts: The proposed building would be seven (7) stories, six (6) above ground, and approximately 71 feet (71’) at the highest point. It would be similar in scale to the adjoining Merrill Gardens facilities to the south and west. Exterior features include a CMU brick façade with windows and canopies. Upper floors would incorporate fiber cement lap and panel siding, window trim, vinyl windows with trim, aluminum panels and asphalt shingles on the roof. The building’s articulation treatments include façade modulations on floors two (2) through six (6), balconies for dwelling units, vertical color and material transitions and roof overhangs. The applicant would be required to meet Urban Design Regulations for overlay District ‘D’ as a component of the land use application. Mitigation Measures: No further mitigation recommended. Nexus: Not applicable. 6. Historic and Cultural Preservation Impacts: The City received public comment from the Duwamish Tribe that the project is located within an impact area that the Tribe considers culturally significant and has a high probability to have unknown archaeological deposits. The project location is within a mile or two (2) of ancestral village sites, stream place names and is in close proximity to at least three (3) known archaeological sites. The DAHP WISAARD predictive model indicates there is a very high risk for encountering cultural resources. As such, the Tribe requests an archaeological survey performed for the project especially if excavation occurs below fill. If any archaeological work or monitoring is performed, notice is requested. The Tribe would also like the opportunity to be present if or when an archaeologist is on site in the event that an artifact or cultural resource is encountered. The current proposal did not receive comment from the Washington State Department of Archaeology and Historic Preservation. Due to the proximity to archeological sites near the project area, staff recommends as a mitigation measure, that the applicant complete an archaeological survey by a qualified professional on the site prior to ground disturbing activities and an Inadvertent Discoveries Plan prepared by a qualified professional. A report identifying the results and any needed next steps shall be submitted with the Inadvertent Discoveries Plan at the DocuSign Envelope ID: E380154C-A526-42C6-9A09-974E2B481BE1 City of Renton Department of Community & Economic Development Camellia Court Apartments Staff Report to the Environmental Review Committee LUA23-000361, ECF, CUP-H, SA-H, MOD Report of December 18, 2023 Page 7 of 8 ERC_CamelliaCourt_Final time of the civil construction permit application for review and approval by the Current Planning Project Manager prior to permit issuance.

Nexus: City of Renton Comprehensive Goals and Policies, L-AA, L-45 and L-46; RCW 27.53 Archaeological Sites and Resources; RCW 27.44 Indian Graves and Records; WAC 197-11 SEPA Rules 7. Transportation Impacts: The proposed project fronts upon Williams Ave S to east and an unnamed alley to the south and west. Williams Ave S is classified as a Minor Arterial with an existing right-of-way width of 60 feet (60’) as measured using the King County Assessor’s Map with an existing paved width of approximately 40 feet. The proposed development triggers frontage improvements along Williams Ave S to include a half foot (0.5’) curb, an eight-foot (8’) planting strip, an eight-foot (8’) sidewalk, street trees and storm drainage improvements; dedication of approximately 15.5 feet (15.5’) is required. The City Transportation section has recommended that the existing curb location and pavement width on the west side of Williams Ave S is sufficient, and a modified minor arterial street standard containing a right of way width of approximately 65-feet is acceptable. The modified street would contain 12-foot sidewalks with 0.5-foot curb with street trees in tree grates; this would align with the frontage improvements along Williams Ave S that were made as part of the adjacent Merrill Gardens project to the south. The unnamed alley to the west has an existing right-of-way of approximately 10 feet (10’) with an existing paved width of approximately 10 feet (10’). Per RMC 4-6-060, the minimum right of way width for an alley is 16-feet; therefore, a dedication of 3-feet of right of way will be required depending on the final survey. Per City code 4-6-060 the alley would need to be 12-feet paved with storm drainage improvements. A Traffic Impact Analysis is required when a project proposal would result in the generation of 20 new a.m. or p.m. peak hour trips. A Traffic Study (Exhibit 14), dated March 2023, was prepared by Kimley- Horn and Associates, Inc. It indicates that the development is estimated to generate 142 new average weekday daily vehicular trips with 18 new trips occurring during the weekday a.m. peak hour and 16 new trips occurring during the weekday p.m. peak hour. Therefore, the project is not required to provide a Traffic Study. The proposal has passed the City’s Traffic Concurrency Test (Exhibit 15) per RMC 4-6-070D, which based upon a test of the citywide Transportation Plan, consideration of growth levels included in the LOS-test Transportation Plan, and future payment of appropriate Transportation Impact Fees. Mitigation Measures: None recommended.
